Distro: TFS 9.63

Olá Xtibianos,

Pedido: Quero Criar um NPC que dê TRADE apenas com players que terminaram X Quest.

Tentativa: No meu Ot 8.60 funciona perfeitamente esse modelo abaixo:

if (getPlayerStorageValue(cid, storage) < 16 and msgcontains(msg, "trade")) then
npcHandler:say("You are not able to negotiate with me, help me every day and then you can do it.", cid)
elseif (getPlayerStorageValue(cid, storage) >= 16 and msgcontains(msg, "trade")) then
 local items = {
  {name="platinum amulet", id=2171, buy=0, sell=2500},
  {name="ring of the sky", id=2123, buy=0, sell=3000},
  {name="ruby necklace", id=2133, buy=0, sell=2000},
  {name="scarab amulet", id=2135, buy=0, sell=200},
  {name="silver brooch", id=2134, buy=0, sell=150},
  {name="terra amulet", id=7887, buy=0, sell=1500},
  {name="doll", id=2110, buy=0, sell=200},
  {name="light shovel", id=5710, buy=0, sell=300},
  {name="pirate voodo doll", id=5810, buy=0, sell=50},
  {name="voodo doll", id=3955, buy=0, sell=400}
 }
openShopWindow(cid, items,
  function(cid, itemid, subType, amount, ignoreCap, inBackpacks)
   customCallbackOnBuy(cid, itemid, subType, amount, ignoreCap, inBackpacks, items)
  end,
  function(cid, itemid, subType, amount, ignoreCap, inBackpacks)
   customCallbackOnSell(cid, itemid, subType, amount, ignoreCap, inBackpacks, items)
  end
 )
npcHandler:say("Of course, just browse through my wares.", cid)
end

Erro: Quando eu uso esse script no 9.63 não é possível comprar items que não são agrupáveis, e o seguinte erro é exibido no console:

[Error - NpcScript Interface]
(Unknown script file)
Description:
data/lib/050-function.lua:447: bad argument #2 to 'error' (number expected, got string)
stack traceback:
   [C]: in function 'error'
   data/lib/050-function.lua:447: in function 'customCallbackOnBuy'
   data/npc/scripts/al dee.lua:50: in function <data/npc/scripts/al dee.lua:49>

O que eu realmente quero: Ficaria muito grato se alguém conseguisse "consertar" essa função para mim, se não der por favor postem outras soluções.

Material Necessário:

function customCallbackOnBuy:

function customCallbackOnBuy(cid, itemid, subType, amount, ignoreCap, inBackpacks, shopWindow)
local shopItem, npcHandler = nil, NpcHandler
for _, item in ipairs(shopWindow) do
 if not item.subType then
  item.subType = (isItemFluidContainer(item.id) == TRUE or isItemStackable(item.id) == TRUE) and 0 or 1
 end
 if(item.id == itemid and (item.subType == subType)) then
  shopItem = item
  break
 end
end

if(shopItem == nil) then
 error("[shopModule.onBuy]", "Item not found on shopItems list")
 return false
end

if(shopItem.buy < 0) then
 error("[shopModule.onSell]", "Attempt to purchase an item which is only sellable")
 return false
end

local backpack, totalCost = 1988, amount * shopItem.buy
if(inBackpacks) then
 totalCost = isItemStackable(itemid) == TRUE and totalCost + 20 or totalCost + (math.max(1, math.floor(amount / getContainerCapById(backpack))) * 20)
end

if(getPlayerMoney(cid) < totalCost) then
 doPlayerSendCancel(cid, npcHandler:parseMessage(npcHandler:getMessage(MESSAGE_NEEDMONEY), {[TAG_PLAYERNAME] = getPlayerName(cid), [TAG_ITEMCOUNT] = amount, [TAG_TOTALCOST] = totalCost, [TAG_ITEMNAME] = shopItem.name}))
 return false
end

local subType = shopItem.subType or isItemFluidContainer(itemid) == TRUE and 0 or 1
local a, b = doNpcSellItem(cid, itemid, amount, subType, ignoreCap, inBackpacks, backpack)
if(a < amount) then
 local msgId = MESSAGE_NEEDMORESPACE
 if(a == 0) then
  msgId = MESSAGE_NEEDSPACE
 end

 doPlayerSendCancel(cid, npcHandler:parseMessage(npcHandler:getMessage(msgId), {[TAG_PLAYERNAME] = getPlayerName(cid), [TAG_ITEMCOUNT] = amount, [TAG_TOTALCOST] = totalCost, [TAG_ITEMNAME] = shopItem.name, [TAG_ITEMCOUNT] = a}))

 if(a > 0) then
  doPlayerRemoveMoney(cid, ((a * shopItem.buy) + (b * 20)))
  return true
 end

 return false
end
doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, npcHandler:parseMessage(npcHandler:getMessage(MESSAGE_BOUGHT), {[TAG_PLAYERNAME] = getPlayerName(cid), [TAG_ITEMCOUNT] = amount, [TAG_TOTALCOST] = totalCost, [TAG_ITEMNAME] = shopItem.name}))
doPlayerRemoveMoney(cid, totalCost)

return true
end

@Vodkart, items agrupáveis estão comprando ao quadrado.

Ex: compro 2 worms, recebo 4,

compro 3 recebo 9.

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

function onCreatureDisappear(cid) npcHandler:onCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg) npcHandler:onCreatureSay(cid, type, msg) end
function onThink() npcHandler:onThink() end
function creatureSayCallback(cid, type, msg)
if(not npcHandler:isFocused(cid)) then
return false
end
local talkUser,msg = NPCHANDLER_CONVbehavior == CONVERSATION_DEFAULT and 0 or cid,string.lower(msg)

 }

local items = {}  
   for _, item in ipairs(trade) do
   items[item.id] = {item_id = item.id, buyPrice = item.buy, sellPrice = item.sell, subType = 0, realName = item.name}
end 
local onBuy = function(cid, item, subType, amount, ignoreCap, inBackpacks)  
  if items[item].buyPrice ~= 0 then  
      doPlayerRemoveMoney(cid, amount * items[item].buyPrice)
if isItemStackable(items[item].item_id) then

else  
      for i = 1, amount do 
          doPlayerAddItem(cid, items[item].item_id, 1)  
      end
end 
  end

doPlayerRemoveItem(cid, items[item].item_id, amount)  
end 
end 
   if msgcontains(msg, 'trade') and getPlayerStorageValue(cid, 784745) > 0 then  
    openShopWindow(cid, trade, onBuy, onSell) 
  else
selfSay("Não vendo nada para você!", cid)  
end
return true
end
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())

@Vodkart agora não está verificando o cap do player, vai comprando e caindo no chão, e não funciona "buy with backpacks", não estou reclamando, desse jeito está otimo, só estou notificando, ok?
